Baicalein treatment does not affect baseline evoked responses or paired-pulse facilitation. (A) Typical superimposed field excitatory postsynaptic potential (fEPSP) recorded from the CA1 region in the presence and absence of 1 µM baicalein by increasing stimulation intensity. (B) Input–output curves illustrating the relationship between the stimulation and evoked response for fEPSPs recorded from control and baicalein-treated slices. No significant differences were observed. (C) Typical fEPSPs are shown from experiments at 50 ms interpulse interval before and after high-frequency stimulation (HFS) stimulation. (D) Paired-pulse facilitation (PPF) was measured by varying the intervals between pairs of stimuli before and after HFS stimulation. No significant differences were observed. Each point was the normalized mean ± SEM of five slices.
